Bissell 7920 not dispensing all of a sudden

\015 Okay, so my friends powered this cleaner and in the midst of using it "it just stopped working." I got it back from them and found that it was clogged in many places full of dog hair. (Apparently, they didn't vaccum the carpet before they tried to clean it. I yi yi!)\015\012\015\012Anyway, I cleared it of all hair/jams, I replaced the pump, and the belts, and water sprayed for about 10 seconds and then quit again on me.It IS pulling water from at least one area...but most of it is "dribbling" into the bottom half of the machine NOT onto the carpet.\015\012\015\012There ARE bubbles in the lines, so I did my best to fill the lines with more liquid...in case air was causing a problem...still no resolution.\015\012\015\012I cleaned out the heater as suggested on here also and no, the hand tool doesn't spray either. Any other suggestions?\015\012\015\012I'm really frustrated but still think it must be something "easy" and would be ********** to have bought new parts, worked on it, and then take it to a repair shop and spend a lot of money on something still pretty simple.\015

Answers :

You could have a pinched line. When you put the top back on, the piston should have been on the bottom of the smart mix valve and in the water only setting. The heater could be plugged, which is in the handle. If water sprays out of the tool hose, then the heatr or line in the handle is clogged. Is the gasket on the water and the soap bottle on the valve at the bottom, it has to be on it not sitting in the hole.Is the top secured all of the way around, sometimes the back will back free and rise up causing problems. Spray nozzles are clogged. Try running a mix of vinegar and water to see if it will unclog it.

Ensure you have water in tank and solution (or water in solution tank). When you start the vacuum up, the pump starts to prime itself. If you have air in the system, it takes a little longer to prime. Allow the vacuum to run for 1 minute before at ...

I posted my problem earlier today that I was having with my Bissell Little Green Machine not dispensing solution, but sucked up no problem. Someone said that the most common problem was a blockage. We put hot water in the reservoir for 15 minutes as advised and it still will not dispense. The fluid is now ''dribbling''so it is better. It is just not spraying. We are able to blow from the end and make bubbles in the reservoir which shows us it is not blocked. Any other suggestions?

Okay. I fixed this on mine. Undo the screws on the handle, right by the trigger. You pull the tubes off the little valve. Push on the button and see if you can blow through the valve. If not, push a pin around in the valve (with it pushed into the ...
Bissell 1720-1 Little Green Wet/Dry Vacuum

I have a Bissell 1623-1 Steam Cleaner.
It will work good for about 2 minutes and then after that it will not dispense cleaning solution on floor or through the hand held wand.I have replaced both drive belts with no improvement.
I have cleaned it and found no obstructions in hoses and spray nozzles, put back together and it still will not dispense.
Is it possible the pump or solenoid is no working?
